Wouldn't put anything past those dipheads but with the destruction of the internal files - real or feigned - it's impossible to prove, as the author admits, through documentary evidence. The only way to adduce a proof is by systematic questioning of the living inhabitants of Pont-Saint-Esprit to determine if there were tourists and/or visitors in the town at the time of the incident and what they did during and after the incident. If it was a CIA "experiment" they would have had to have observers for data collection.
Without such a non-paranoid 'explanation' can be made: the Sandoz and CIA conversations were part of the known MK-ULTRA Project but rather than the CIA causing the incident they used it as a way to gather data when it happened.
Though not probative, I think many of the posts in the BB thread I linked to above make a pretty compelling circumstantial case for rye ergot poisoning. The fact is that what we're experiencing right now is a top-down disaster. -Paul Krugman
